l v A Application filed June 4,

To aZZ whom it may concern:

Be it known that we, WILLIAM D. PFRoM- MER, a citizen of the United States, residing at West Berlin, in the county of Camden and State of New Jersey, and FREDERIC W. ADAMS, a citizen of the United States, resid ing at Milbourne, in the county of Delaware and State of Pennsylvania, have jointly invented a certain new and useful Sound-Con- Veyer for Talking-Machines, of which the following is a specification.

The principal objects of the present invention are, first, to provide a simple, eificient and satisfactory sound conveyer adapted to be easily adjusted for playing records of all the kinds that are usually to be found in the market; and second, to insure alinement of the stylus with the axis of the tone arm in each of the various adjustments of the device for playing different records.

The invention will be claimed at the end hereof, but will be first described in connection with the embodiment of it selected for illustration in the accompanying drawings, forming parthereof and in which Figure 1, is a top or plan view of a sound conveyer embodying features of the invention.

Fig. 2, is a side view of the same.

Fig. 3, is a view principally in section illustrating details of construction.

Figs. 4 and 5 are plan and perspective views illustrating the device adjusted for use with a Victor record.

Figs. 6 and 7 are similar views of the device adjusted for use with a Path record, and

Figs. 8 and 9 are similar views of the device adjusted for use with an Edison record.

In the drawings 1 is a tone arm mounted as usual to turn about the vertical axis A, Fig. 1. There are two elbows 2 and 3 pivoted together as at 4 and they constitute a goose-neck. The pivot at 4 is shown to con sist of threadedextensions which are loose to turn one in respect to the other. There are means for connecting one end of the goose-neck on the end of the tone arm in such a way that the goose neck is turnably adjustable about the horizontal axis, Fig. 2, of the tone arm. These means are shown to comprise overlapping extensions fitted one within the other and a pin-and-slot connecfspecification of LettersPatent.

tion 5. 6, is an elbow extension having a curved arm 7 and a laterally projecting sound box receiving neck 8. There are means for turnably adjusting the end of the curved arm 7 on the free end of the gooseneck and these means are shown to comprise overlapping extensions and a pin-and-slot connection 9.

Asshown in Figs. 4 and 5, the described parts of the sound conveyer are relatively adjusted by turning them at the means generally indicated at 5 and 9 in respect to each other into the positions there shown. In those figures it will be noted that the stylus 10 is arranged or lies substantially in the longer axis'of the tone arm 1, which is advantageous in the matter of re-producing sound and it will also be noted that the stylus and sound-box 11 are in position for playing Victor or other zig-zag records.

As shown'in Figs. 6 and 7 the described parts are so relatively adjusted that the sound conveyer is adapted for use in playing so-called Path records which are records of the hill-and-dale variety, made with the stylus oblique to the plane of the record, and in this case it will be noted that the stylus 10 is in substantially the plane of the longitudina l axis of the tone arm.

As shown in Figs. 8 and 9, the parts of the described sound conveyer are relatively adjusted for use in connection with the Edison or hill-and-dale records, made with the stylus perpendicular to the plane of the record, and in this case it will be noted that the stylus or needle 10 is perpendicular to the plane of the record.

While the connection at 4 constitutes a pivot, the connections at 5 and 9 while turnable are adapted for the parts to remain in any position in which they are turned during the use of the sound conveyer and until the parts are adjusted to a new position.

To get the device from the position shown in Figs. 1 and 2 into the position shown in Fig. 9, all that is required is the single manual manipulation of turning the part 7 on the part 3 through 90 which brings the opening 8 into position to face the horizontal in Fig. 2. In other words, in Fig. 2 the opening 8 is turned out of the plane of the paper toward you. To get the parts shown in Figs. 1 and 2 into the position shown in Fig. 7, the joint at 5 is the only part that requires manual manipulation. In all cases the playing joint at 4 is'free to Work.

What We claim is: 1

A talking machine sound 3 conveyer comprising the combination of a tone arm turnable about a vertical axis only, right angle elbows pivoted together to provide a playing joint and constituting a goose-neck means 10 for turnably adjusting one end of the gooseneck on theend of the tone arm, an elbow extension having a curved arm and a latand means for tufnablyadjusting the free end of the elbow extension on the free end .of the goose-neck, substantially as described.
